There is now a new version of the poll that includes, Schlick, Duhem, Hull, Polyani, and David Lewis.

For my money, I have Reichenbach and Hempel in the top spots. The set of issues that we address today in philosophy of science -- confirmation, explanation, causation, probability, realism, space and time, interpretation of QM -- owe more to these two than to any others.

If the criterion were impact beyond philosophy of science, then I'd have to go with Kuhn and Popper.
